Hi guys,
i have some serious problems with the fillets of my turbine (<90°). I've tried to shape the fillet with an o-grid several times , but without any success. I've attached some pics. Which blocks and which faces do i have to choose to create the blocking on pic 4 (blocking_fillet)? Last two pics shows the blocking and scan plane from a similar turbine. Thx in advance.

Still not solved my problems at hub/blade (fillet) and gap (between leading edge and heatshield). Could anyone please help me?
I become desperate. I tried it several times without success. Again: i need an o-grid to resolve the fillet between hub and blade and I didn't get managed to block the gap ( maybe the edges of the o-grid in front of the leading edge were not associated in the correct way to the heatshield/stator). I would be glad to have your help in blocking or just an explanation. Thx guys. Blocking and tin-files: http://www.file-upload.net/download-...1/cfd.zip.html Finally fixed all problems! Premesh looks very nice now. I will make a detailed report with some pics at the weekend for those, how has similar problems (geometry). Last edited by energy382; January 26, 2012 at 13:25. |

did you make new surfaces and curves where you made the associations, coz when I checked your files , I noticed similar problem, and I am wondering where would you associate the edges?
1 more thing, why did you make the two edges in the tip gap and how did you do it? |

Hey!
sorry, it takes me a time to answer your question. With the two edges in the tip gap I created an GGI (nodes didn't match there as you can see). I've splitted vertices and then associated them to the curve. That's the way i made the interface in the middle of the tip. |

sorry, took me a while to answer your question. I made some screenshots to show, how i made the grid interface on the tip. I hope it's comprehensible.
